Plant-derived compounds as potential candidates for atrial fibrillation drug discovery: A review on phytochemicals with atrial-selective activity.
Review in Daru : journal of Faculty of Pharmacy, Tehran University of Medical Sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesAtrial fibrillation (AF), the most prevalent type of cardiac arrhythmia, is associated with high morbidity and mortality. The pharmacological management of AF is still challenging due to the risk of life-threatening ventricular arrhythmias caused by non-selective antiarrhythmic drugs. Therefore, the search for safer and more selective anti-AF medications is ongoing. In this study, we summarized phytochemicals with atrial-selective properties as potential candidates for AF drug discovery. EVIDENCE ACQUISITION: PubMed, Embase, Web of Science, and Scopus were searched using relevant keywords, ultimately identifying sixteen phytochemicals with demonstrated effects on atrial-selective anti-AF targets.
resultsAcross the included studies, phytochemicals were reported to modulate several atrial-selective ion channels, including voltage-gated K+ channel 1.5, voltage-gated Na+ channel 1.5, and G-protein-activated, inward rectifying K+ channel 1 and 4, with some compounds affecting more than one target. The most investigated phytochemicals were acacetin, resveratrol, and its derivative C1, and eleutheroside B, all of which demonstrated anti-AF effects in association with their activity on atrial-selective pathways. Acacetin and resveratrol derivatives exerted anti-AF effects through modulation of multiple atrial-selective ion channels.
conclusionThe findings of this study highlight several promising molecular targets for atrial-selective anti-AF drug development. Among these, acacetin and resveratrol derivatives show notable potential due to their ability to modulate multiple atrial-selective ion channels, supporting their further evaluation as lead compounds.
